Abstract

Injection molding a tread on an annular tire casing (44) positioned in a mold (10') by introducing a fluid molding compound (76',78') at high pressures and high temperatures into a tread molding space (105) through runner passages (114) extending from an edge (116) to a centerplane (20'-20') of the mold (10') and having gates (118) opening into the tread molding space (105). Alternatively the runner passages (56,58) may be defined by annular runner surfaces (60,62,64,66) in communication with the tread molding space (48) through annular gates (52,54). The fluid molding compound (76,78) may be ejected from annular transfer recesses (68,70) in the mold (10) by squeeze rings (84,86) movable into the transfer recesses (68,70) to introduce the fluid molding compound (76,78) into the runner passages (56,58).
